I exchanged the HDD in my 2007 MacBook Pro and removed the dvd-drive because it was making terrible noise everytime I booted the MacBook.

The new HDD is a Corsair Force F120 SATA SSD.

Everytime I try to launch an OSX Lion installation disk or USB stick I get the grey prohibitory sign and the machine shuts down after a while.

Since I didn't format the SSD beforehand there is still Windows 7 on it. It shows the white progress bar with the message "Windows is loading files" but never finishes it. I don't want Windows on that machine, just thought this fact may be important.

Any ideas what is wrong?
